Asus GeForce RTX 4090 ROG Strix BTF OC (ROG-STRIX-RTX4090-O24G-BTF-GAMING)

Quite an expensive and extremely powerful flagship-level video card from the acclaimed 4000th line of NVIDIA GeForce video cards. It delivers extreme performance and efficiency whether as part of a gaming PC or as a key workstation element for AI, media processing, and more. It features 24GB of GDDR6X 384-bit VRAM for high bandwidth up to 21 Gbps. The video card uses 16384 CUDA cores and operates at frequencies up to 2640 MHz in Boost mode.

The main feature of this model is the use of the Graphics Card High-Power (GC-HPWR) Gold Finger connector, which allows up to 600 W to be transferred through a dedicated slot on ASUS BTF motherboards, eliminating the need for visible external power connectors. This improves the aesthetics of the build and prevents the card from sagging. The proprietary cooling system includes three Axial-tech fans, which increase airflow by 23% compared to previous generations of Asus graphics card cooling systems.

Fans automatically turn off when temperatures drop below 50 degrees, ensuring quiet operation at low loads. The patented vapor chamber and heat pipes provide efficient cooling, reducing GPU temperatures by up to 5 degrees at 500 W thermal load. The video card supports modern NVIDIA developments in the field of post-processing and image optimization: separate next-generation RT cores are responsible for ray tracing, and a separate tensor unit helps improve performance using the DLSS 3 “upscaler” and its built-in frame generation system. Considering that the raw power of the graphics card is more than enough for 4K gaming, DLSS and FrameGen will be useful primarily when upscaling to 8K resolution or demanding VR games.
